Every one of us produces garbage of one kind or another. Some of the garbage is thrown into the sea. Some is burnt or buried under the ground. Every year we need to find about 800.000 cubic meters of empty land just to bury the garbage.

This is the same as filling one football stadium with garbage up to 20 meters high! This garbage damages the environment. Although a lot of garbage is buried in the ground, some of it gets blown about in the wind. Also, when garbage is burnt, poisonous gases are given off into the air. The garbage thrown into the sea will pollute the water.

What can we do about these problems? One very easy answer is to produce less garbage. We can recycle things made from glass and paper as well as tin cans. People can refuse to take the plastic bags from the shops and supermarkets by bringing with them their own bags or baskets when they go shopping.

The government should tell people about the dangers of garbage pollution. Education is perhaps the most important factor for keeping our environment healthy for the future.
